Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449126, here are decompositions:

  • 43 + 31449083 = 31449126
  • 73 + 31449053 = 31449126
  • 83 + 31449043 = 31449126
  • 89 + 31449037 = 31449126
  • 97 + 31449029 = 31449126
  • 109 + 31449017 = 31449126
  • 139 + 31448987 = 31449126
  • 223 + 31448903 = 31449126

Showing the first eight; more decompositions exist.
